Food security concerns are currently escalating in sub-Saharan Africa (SSA) due to poor soil management practices on the fragile soils. This review describes role of organic resources acting both as amendments and fertilizers improving nutrient status productivity potentials SSA. The use has achieved significant strides fertility many agro-ecological zones Balanced fertilization soils through synchronized supply adequate nutrients growing crops well increasing matter content over long term...

The study compared the nutritive value of Carica papaya L. fruit at different ripening stages with aim advising consumers and biological world when best to consume fruit.Proximate, mineral vitamin analysis were carried out on pulp, peel seeds fruits.Results showed that unripe is a good source carbohydrates, vitamins proteins, content decreases as it ripens.Very ripe not protein because contains more protein.The C hard very pawpaw was found be fairly high.Papaya A elements (Ca, Mg, Na...

A greenhouse experiment was conducted to study the relative effect of organic and inorganic fertilizers on growth okra (Abelmoschus esculentus). The consisted four treatments. Cow dung poultry droppings were applied at rates 2.5 kg per 10 soil one week before sowing, while NPK fertilizer (15:15:15) rate 6 g three weeks after sowing. treatments laid in a completely randomized design with replications. Plant assessed using plant height, fresh weight, leaf area dry weight. application cow dung,...

Abstract Background: Stimulatory efficacy of spent mushroom compost (SMC) cannot be overemphasized. Aims: In this study, the effect SMC on phytoremediation and plant's response to heavy metal polluted soil was investigated suggested for establishment feasible remediation. Methods: Heavy (80 kg) sterilized at 121°C in sterilizer 30 min repeated four more times remove microbial interference. Five kg packed into pots supplemented with Pleurotus ostreatus different concentrations 10, 20, 30,...

Background.Many companies in Nigeria generate industrial effluents, including heavy metals. These metals can be accumulated by biota such as mushrooms, which are then eaten the populace.Objectives.The present study investigates metal content of wild mushrooms order to educate local population on safety their consumption.Methods.Seven different species (Cortinarius melliolens, Chlorophyllum brunneum, Pleurotus florida, Volvariella speciosa, Cantharellus cibarius, Entoloma spp and Coprinus...

Screen house experiments were carried out to examine the effects of aqueous leaf extracts Tithonia diversifolia (Ti) and Vernonia amygdalina (Ve), as well NPK fertilizer (15-15-15) on germination, growth development maize. Fresh leaves collected, washed with tap water, chopped pounded, soaked in distilled water filtered. The two filtrates used prepare at 50 100% w/v. Four maize seeds placed Petri dishes laid a completely randomized design five replicates. In every dish 10 ml extract per...

Soil heavy metals pollution is of global concern in view their flow through the food chain. The convectional, physical, and chemical approaches to remediate polluted soils are usually expensive not eco-friendly. Phytoextraction a promising alternative because cost effectiveness eco-friendliness. Therefore, this study was designed determine abilities Chromolaena odorata (Co) Tithonia diversifolia (Td) extract from soil. analysis done part per million (ppm) before Td Co were grown separately...

Ibodi Monkey Forest (IMF) is one of the least studied forest reserves in Nigeria. This being increasingly subjected to anthropic actions. There dearth information on Carbon sequestration potential this forest. We investigated distribution patterns pools and overall potentials different physiognomies Forest. identified three IMF based levels anthropogenic interferences as follows: Regrowth (RF), Cocoa Plantation (CP), Tree Fallow (TF). Four plots (25 × 25 m2) were randomly selected within...

This study investigated the effects of inorganic fertilizer (N15P15K15) amendments on crude oil uptake by water hyacinth. Experimental units (water hyacinth grown in fresh water) were spiked with 0, 20, 40 and 60 mg/L oil. After 24 h, they randomly assigned at three different concentrations; 6 10 mg/L. Crude degradation absorption determined measuring total petroleum hydrocarbon (TPH) column hyacinth, respectively. The measurements taken monthly for six months (February–August 2010). results...

This study investigated the potential health risk associated with consumption of metal-laden mushrooms in Nigeria. Concentrations Pb, Cd, Cr, Cu, Ni, Zn and Al wild collected from Nigerian environment were measured using atomic absorption spectrometer. Also, systematic analysis articles on metal accumulation Nigeria obtained scientific databases. Using hazard model indices, concentration evaluated for their carcinogenic non-carcinogenic when consumed by adults children. respectively, had...

A B S T R C The balanced use of inorganic amendments to enhance effective crop production for developing world economies like Nigeria is paramount achieve her Millennium Development Goals (MDGs) its teeming population. Thus this study was carried out assess the relative growth performances a major food under different regimes fertilizer application. Field and Green House experiments were two Cycles Zea mays L.
